I don't think it's the poly count that everyone's appreciating here. It's the detail they put into the systems and behaviour that makes you feel like you're operating a real aircraft. I don't think Oleg's Spit models will need much improving, inside or outside. I would like to see a faithful reproduction of the systems though and some real sampled sound might be nice too.
I've already sent a request to A2A regarding future integration with COD....haven't had any reply though. Wouldn't harm if some of you guys did the same so they know there's real interest:
